DESCRIPTION:Speakers: Vsevolod Chestnov (Oxford)\n\nDifferential equations
  are one of the main tools for the study of Feynman integrals. In this tal
 k\, I will discuss an algebraic approach to constructing such equations ba
 sed on D-module theory. Starting from parametric representations\, one can
  construct differential operators that annihilate the corresponding integr
 als. These annihilators define a D-module and can also be used to derive f
 irst-order systems of differential equations for suitable finite bases of 
 integrals. I will then explain how such systems can be restricted to singu
 lar limits\, leading to systematic asymptotic expansions involving powers 
 and logarithms. I will illustrate the general pipeline from annihilators t
 o expansions with simple examples of hypergeometric and Feynman integrals.
